TECHNICAL FIELD

The present invention relates to a user authentication system and method for login and financial transactions such as payment settlement, stock trading, and transfers, and more particularly, to a mobile cross-authentication system and method for performing mutual authentication during online authentication, in which an authentication server device generates an online authentication code (Ocode) and a mobile authentication code (Mcode), the online authentication code (Ocode) is provided to a user's computer terminal device, the mobile authentication code (Mcode) is provided to a user's portable terminal device, the online authentication code (Ocode) received by the user's computer terminal device is input into the user's portable terminal device to be transmitted to the authentication server device, and the mobile authentication code (Mcode) received by the user's portable terminal device is input into the user's computer terminal device to be transmitted to the authentication server device.

BACKGROUND ART

As the Internet becomes popular and general, people are receiving various services through the Internet. People purchase products through e-commerce, use Internet banking such as an account transfer, and access various websites to receive information.
As described above, in order to have various online services, people are accustomed to a method of inputting and storing personal information and financial information through the Internet. Financial fraudsters are exploiting the above method so that important personal information is hacked and leaked, thereby causing mental and financial damage to people.
In order to prevent such personal information leakage and financial fraud, authentication techniques, in which digital signature authentication based on an accredited certificate, a one-time password (OTP), mobile phone authentication, automatic response system (ARS) authentication, or the like is added to or combined with a technique using identification (ID) and a password, have been applied basically.
However, a digital signature authentication technique has been threatened with security thereof due to a leakage and theft of an accredited certificate, and in order to solve this problem, although a technique of safely storing an accredited certificate using a security token or a universal subscriber identity module (USIM) is disclosed in the prior laid-open patent documentation 10-2012-0100342 and the prior laid-open patent documentation 10-2012-0071945, there has been a problem in that the burden of using a separate hardware device is increased and the techniques have to be dependent on a specific hardware module.
In addition, due to the emergence of hacking techniques such as memory hacking, the financial authentication methods that use accredited certificates and OTP devices have also become ineffective against financial fraud, resulting in financial fraud and social problems.
Financial fraud or the like occurs in existing mobile phone authentication methods due to steal of a short message service (SMS) authentication code such as smishing, and even in the case of existing ARS authentication, problems caused by call forwarding have been revealed and a security threat is posed.
In addition, although a virtual card number is provided in the case of app card methods, because there is a limitation in that an application has to be downloaded to a smart phone, usability of the app card methods is lowered, and the app card methods cannot be applied as an authentication method of a user using a general mobile phone.

DETAILED DESCRIPTION

Hereinafter, a configuration and operation of a mobile cross-authentication system according to the present invention and an authentication method of the system will be described with reference to the accompanying drawings.
Technical Improvements & Practical Applications of Embodiments
Once a user requests an authentication by using a computer terminal, an authentication server device generates two different codes, which are an online authentication code (“Ocode”) and a mobile authentication code (“Mcode”). The authentication server device transmits the Ocode to the computer terminal device, and transmits the Mcode to the portable terminal device.
In generating the Ocode and the Mcode, one-time temporal random code generation scheme can be used by the authentication server device. For example, random code generation scheme can be truly random hardware random-number generators (HRNGS), which generate random numbers as a function of current value of some physical environment attribute that is constantly changing in a manner that is practically impossible to model, or pseudorandom number generators (PRNGS), which generate numbers that look random, but are actually deterministic, and can be reproduced if the state of the PRNG is known. The pseudorandom number generator (PRNG), also known as a deterministic random bit generator (DRBG) is an algorithm for generating a sequence of numbers whose properties approximate the properties of sequences of random numbers, can be used by a computing device described in the present disclosure. PRNGs are central in applications such as simulations (e.g., for the Monte Carlo method), electronic games (e.g., for procedural generation), and cryptography. Cryptographic applications require the output not to be predictable from earlier outputs, and more elaborate algorithms, which do not inherit the linearity of simpler PRNGs, are needed.
The present disclosure primarily has three aspects for improving the cyber security technologies related to transactions using the portable terminal device.
First, for one authentication, two different codes (i.e., the Ocode and the Mcode) are generated and transmitted to two different devices (the computer terminal device and the portable terminal device), and then, the code sent to the computer terminal device is transmitted to the portable terminal device, and the code sent to the portable terminal device is transmitted to the computer terminal device, and then, those code are cross-authenticated.
In this aspect, even one code is leaked, the authentication cannot be succeeded. Even one device is stolen, the authentication cannot be succeeded. Even two codes are leaked, the two devices (the computer terminal device and the portable terminal device) are not stolen, the authentication cannot be succeeded. Thus, the cyber security technologies can be improved by this aspect.
Second, portable terminal device identification information is requested in requesting an authentication. In conventional art, the portable terminal device identification information is stored in the user information database. However, in conventional art, when the portable terminal device is changed, the user information database must be updated to re-register the stored portable terminal device identification information. By contract, in the present disclosure, portable terminal device identification information is requested in requesting an authentication. Thus, it is more convenient to a user and it can save time and resource. Thus, the cyber security technologies can be improved by this aspect.
Third, three-stage authentications are required—i) Ocode authentication; ii) Mcode authentication; iii) portable terminal device identification information authentication. The cyber security technologies can further be improved by this aspect.
It can be seen from the previous description that, when completing the payment service by using the three-stage authentications in the present application, A user may use Ocode and Mcode temporarily generated by the devices instead of the user's personal information (e.g., real card number). Even if an unauthorized person steals the user's smartphone, the unauthorized person cannot complete the payment operation because two different codes (i.e., the Ocode and the Mcode) cannot be matched, thereby ensuring property security of the user. In addition, because the three-stage authentications in the present application does not need to carry the user's real card number printed on an actual credit card or real ID (e.g., Social Security Number), a payment operation can be performed and improve user experience and flexibility of the described implementation of services.
Implementation of the present application provide methods and apparatuses for implementing services, such as making a payment by using a one-time generated code.
In some embodiments, the portable terminal device identification information is used (i) for transmitting the Mcode to the portable terminal device to perform cross-authentication through two different devices; (ii) for verifying a user by retrieving an authentication code generated by the authentication server device when a code is verified (the authentication server device may store generated codes along with mapping information with terminal devices); and (iii) for verifying matching of a portable terminal device number (Dev_no) with the received telephone number of the portable terminal device identification information.
Dev_no can be various types of information that uniquely identifies each portable terminal device such as, a telephone number, device serial number, IMEI (International Mobile Equipment Identity), and MEID (Mobile Equipment Identifier).
When the Ocode is transmitted using a SMS message, the authentication server device can obtain the sender's telephone number from SMS, but cannot obtain other information such as device serial number, IMEI (International Mobile Equipment Identity), and MEID (Mobile Equipment Identifier). In this case, it can be configured to retrieve other information such as device serial number, IMEI (International Mobile Equipment Identity), and MEID (Mobile Equipment Identifier) from the database of the authentication server device.
When the Ocode is transmitted through the mobile app, the information such as a telephone number, device serial number, IMEI (International Mobile Equipment Identity), and MEID (Mobile Equipment Identifier) can be obtained.
In the present disclosure, the portable terminal device identification information (Tel_no) is information entered by a user input, and the portable terminal device number (Dev_no) is information detected and obtained when the Ocode is received from the portable terminal device or information stored in a database of the authentication server device and automatically retrieved. If the portable terminal device number (Dev_no) is not matched with the received portable terminal device identification information, an authentication would be failed.
When Ocode is received by the portable terminal device, and the portable terminal device transmits the Ocode to the authentication server device, the authentication server device can detect and obtain the portable terminal device number (Dev_no) when the authentication server receives the Ocode or the authentication server device can acquire Dev_no from the database of the authentication server. The authentication server device may verify whether Dev_no is matched with the portable terminal device identification information received from the user.

Wireless communications circuitry 270 may include processing circuitry (sometimes referred to as baseband processors) that is used in implementing communications protocols to support interactions with external equipment. In one suitable arrangement, each baseband processor may be coupled to one respective transceiver circuit. In other suitable arrangements, a baseband processor may be shared among one or more transceiver circuits. The baseband processing circuitry and the main processor 251 are sometimes referred to collectively as control circuitry.
The baseband processing circuitry may receive digital data to be transmitted from processor 251 and may supply corresponding signals to a wireless transmitter for wireless transmission. During signal reception operations, a wireless receiver may receive radio-frequency signals from external sources (e.g., wireless base stations, wireless access points, GPS satellites, NFC readers, etc.). The baseband processing circuitry may convert signals received from the wireless receiver into corresponding digital data. In general, the functions of the baseband processing circuitry are provided by one or more integrated circuits. Communications protocols that may be implemented using the baseband processing circuitry may include internet protocols, wireless local area network protocols (e.g., IEEE 802.11 protocols—sometimes referred to as Wi-Fi®), protocols for other short-range wireless communications links such as the Bluetooth® protocol, cellular telephone protocols, MIMO protocols, antenna diversity protocols, etc.

Long-range links are typically used to convey data over thousands of feet or miles. Short-range links are typically used to convey data over tens or hundreds of feet. Near-field communications links typically are generally formed over distances of 20 cm or less (i.e., device 10 must be placed in the vicinity of the near-field communications reader for effective communications). These examples are merely illustrative and do not serve to limit the scope of the present invention. If desired, wireless communications circuitry 270 may be configured to support any suitable wireless communications protocols.
Wireless communications circuitry 270 may also include antennas. The antennas may be formed using any suitable antenna types. For example, the antennas may include antennas with resonating elements that are formed from loop antenna structures, patch antenna structures, inverted-F antenna structures, slot antenna structures, planar inverted-F antenna structures, helical antenna structures, hybrids of these designs, etc. Different types of antennas may be used for different bands and combinations of bands. For example, one type of antenna may be used in forming a local wireless link antenna and another type of antenna may be used in forming a remote wireless link antenna. In addition to supporting cellular telephone communications, wireless local area network communications, and other far-field wireless communications, the structures of the antennas may be used in supporting near-field communications. The structures of the antennas may also be used in gathering proximity sensor signals (e.g., capacitive proximity sensor signals).
Input-output circuitry 254 may also include an interface circuit 266 for linking applications processor 251 to external elements.
Secure enclave processor 252 may include one or more processors, a secure boot read-only memory (ROM), one or more security peripherals, and/or other components. The security peripherals may include hardware configured to assist in the secure services performed by processor 252, such as authentication hardware for implementing various user authentication techniques (e.g., a biometric sensor such as a fingerprint sensor, a retinal sensor, a palm sensor, a signature-identification sensor, just to name a few), encryption hardware configured to perform encryption, secure-interface controllers configured to communicate over the secure interface to other components, etc. Secure enclave processor 252 may only be accessed via a carefully controlled interface, thus forming a secure enclave for processor 252 and its peripheral components. Managed in this way, direct unauthorized access to components within secure enclave processor 252 may be prevented.
